SPECIFICATION forming part of Letters Patent No. 573,657, dated December 22, 1896.

Application filed August 2 91 1 8 9 5 [0 all whom it may concern.-

Be it known that we, ALOIS L. HOCHHOL- ZER and ROBERT E. HILL, residing at Rome, in the county of Floyd, State of Georgia, and JOHN D. RIGGS, residing at Selma, in the county of Dallas, State of Alabama, citizens of the United States, have invented certain new and useful Improvements in Oiling-(lups, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to automatic oilfeeding cups designed for use in connection with machinery of various kinds and classes; and the object thereof is to provide a simple and effective device of this class in which the flow of the oil may be regulated to any desired extent by means of a spring-controlled valve; and with this and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which Figure 1 is a side elevation of our improved oil-cup; Fig.2, a central vertical section thereof; Fig. 3, a side elevation of amodified form of construction, and Fig. 4 a side elevation of a part of the construction shown in Fig. 3.

In the practice of our invention we employ a cup A, having a base B provided with a screw-threaded shank C, in which is formed a central vertical bore D, in which is placed a spiral spring E. The spiral spring E rests upon a securing-plug E, which is provided with a small vertical bore j, which communicates with the central bore D of the shank C, and said central bore D is enlarged at its upper end, forming a chamber d, at the bottom of which is an annular shoulder or rest cl, and placed within the chamber d is an automatic stop-valve G.

The inner walls of the upper part of the cup A are screw-threaded, and connected therewith is a cap H, having a depending rim it provided with a screw-thread on its outer surface, and said cap H is also preferably provided with an annular outwardly-directed rim Serial No. 560,900- (No model.)

or flange h. Formed centrally in the cap H is a hole or opening K, through whichpasses a shaft 70, the upper end of which is screwthreaded and provided with a jam-nut 7c.

The shaft K rests upon the valve G, and the weight thereof is sufficient to keep the valve seated and thus prevent the oil from flowing through the plug F, and the object of the jam-nut k is to regulate the vertical position of the shaft K and of the valve G, which in the absence of the shaft K would be held above its seat by the spiral spring E, and it will be readily seen that by means of the jamnut 7t the distance of said valve G from its seat may be regulated as desired and at all times, and thus the amount of oil passing through the plug F may be regulated to suit the requirements of any and all conditions.

In the construction shown in Fig. 3 the cup A is provided with a removable cap or cover H, which surrounds the cup, and through the top of this cap or cover passes the shaft It, as hereinbefore described, and mounted thereon is the jam-nut It. The base B of the cup A is provided with an annular shoulder a, on which the cap or cover H rests, and formed therein is a cavity or recess a, and connected with said base is a spring L, the free end of which is provided with an upwardly-directed projection L and a downwardly-directed hook or extension L which is adapted to be forced into the cavity or recess a. Secured to the cap or cover H, at one side thereof, is a pin or plug M, and formed in the bottom of the cap or cover H, at one side thereof, is a recess N, from whichextends a slot 0, and in operation the cap or cover is inserted over the cup so that the plug or pin M will enter said recess N, and the cap or cover is then turned or may be turned so that the plug or pin M will enter the slot 0, and in this operation the base of the cap or cover will rest upon the spring L and force it into the cavity or recess a, and as the cap or cover is turned the projection L of the spring L will enter a notch or recess P, formed in the bottom thereof, and in this position the cap or cover will be held by said spring L, the hook or projection L of which also enters the cavity or recess a, as clearly shown in Fig. l. The operation of this form of construction is the same as that hereinbefore described and needs no further description.

In either form of construction the position of the valve G is regulated by the shaft 70, and the amount of pressure upon the valve G and the consequent position of said valve will be regulated by the jam-nut it. It will also be seen that in the form of construct-ion shown in Figs. 3 and 4 the position of the valve may be regulated by simply turning the cap or cover as the shaft K may be raised or lowered by the operation of the plug or pin M in the slot 0, which may be formed at any desired angle or inclination.

lVith our improved construction a great saving of oil may be efiected, and, as will be readily understood, the flow of oil may be entirely out off whenever desired, and, as will also be understood, the automatic valve may be cleaned or any grit or dirt which may collect thereon may be readily removed by removing the cap or cover.

Our improved oil-cup is designed for use on locomotives as well as on stationary ma chinery and for the purpose of oiling the rods, eccentrics, stuffing-boxes, and all other parts thereof where such devices are required.

Our invention is not limited to the forms of construction herein shown and described,or to the combination and arrangement thereof, and we therefore reserve the right to make all such alterations therein and modifications thereof as fairly come within the scope of the invention.

Having fully described our invention, We claim and desire to secure by Letters Patent-- 1. The combination in an oiling-cup of the character described, of the base having a central bore in which is located a spring, a plug provided with a central bore, and upon which rests said spring, a valve supported by said spring and adapted to close the passage through the base of the cup, a cap for said cup and a spindle passing through said cap and adapted to rest upon said valve, the upper end of the said spindle being screwthreaded and carrying a jam-nut, substantially as described.

2. An oiling device of the character described consisting of the cup A, provided with a removable cap H, said cap being provided with a spindleopening, a spindle passing through said cap screw-threaded upon the upper portion upon which is secured a jamnut, and the base B of the cup being provided with an annular shoulder a, upon which the cap H rests, a spiral spring L connected with said base, the free end of which spring is provided with an upward projection L, and downwardly-directed hook L which is adapted to enter cavity a, a cover H, provided at one side with a pin M which is adapted to engage the recess N in the above with which communicates a slot 0, said base being provided with a screw-threaded shank having a central bore in which is secured a tubular plug, substantially as and for the purpose set forth.

I11 testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 22d day of August, 1895.
